Answer from: brittanysanders

D. 36

Step-by-step explanation:

The square of half the x-coefficient must be added. That value is (12/2)² = 36.

You're trying to create a trinomial of the form ...

... (a + b)² = a² +2ab +b²

where a = x, and 2b = 12.

The number you need to add is b² = (2b/2)² = (12/2)² = 36.
